Global stabilisation of continuous bioreactors: tools for analysis and design of feeding laws

De Battista, Hernán; Jamilis, M.; Garelli, Fabricio; Picó, Jesús (Elsevier, 2018-03)

[EN] This work revisits the dynamic behaviour of stirred continuous reactors in which a single bioreaction with unknown kinetics occurs. Conditions on the feeding strategy to avoid washing out the biomass and falling in ...
Integrated sliding-mode algorithms in robot tracking applications

Gracia Calandin, Luis Ignacio; Garelli, Fabricio; Sala Piqueras, Antonio (Elsevier, 2013-02)

An integrated solution based on sliding mode ideas is proposed for robotic trajectory tracking. The proposal includes three sliding-mode algorithms for speed auto-regulation, path conditioning and redundancy resolution in ...
Reaction rate reconstruction from biomass concentration measurement in bioreactors using modified second-order sliding mode algorithms

De Battista, Hernán; Picó Marco, Jesús Andrés; Garelli, Fabricio; Navarro Herrero, José Luís (Springer Verlag (Germany), 2012-11)

This paper deals with the estimation of unknown signals in bioreactors using sliding observers. Particular attention is drawn to estimate the specific growth rate of microorganisms from measurement of biomass ...
Robot coordination using task-priority and sliding-mode techniques

Gracia Calandin, Luis Ignacio; Sala Piqueras, Antonio; Garelli, Fabricio (Elsevier, 2014-02)

In this work, an approach based on task-priority redundancy resolution and sliding mode ideas is proposed for robot coordination. In particular, equality and inequality constraints representing the coordination of the ...
Second-order sliding mode observer for multiple kinetic rates estimation in bioprocesses

Nuñez, Sebastián; Battista, Hernán de; Garelli, Fabricio; Vignoni, Alejandro; Picó Marco, Jesús Andrés (Elsevier, 2013-09)

[EN] Specific kinetic rates are key variables regarding metabolic activity in bioprocesses. They are non-linear functions of concentrations and operating conditions and therefore of difficult access for process control. ...
Simulación de un algoritmo para controlar el nivel en tolva ante alimentación discontinua de caña

Garelli, Fabricio; Ramírez M., Mercedes; Domínguez C., Ariel; Angulo A., Modesto (Universitat Politècnica de València, 2009-07-13)

[ES] Los actuales métodos de control del transporte y preparación de la materia prima provocan graves problemas de discontinuidad en la alimentación al tren de molinos de caña en la industria azucarera en Cuba. La introducción ...
Sliding Mode Reference Coordination of Constrained Feedback Systems

Vignoni, Alejandro; Garelli, Fabricio; Picó, Jesús (Hindawi Limited, 2013)

[EN] This paper addresses the problem of coordinating dynamical systems with possibly different dynamics (e.g., linear and nonlinear, different orders, constraints, etc.) to achieve some desired collective behavior under ...
Specific growth rate estimation in (fed-)batch bioreactors using second-order sliding observers

De Battista, Hernán; Picó, Jesús; Garelli, Fabricio; Vignoni, Alejandro (ELSEVIER SCI LTD, 2011-08)

[EN] This paper addresses the estimation of specific growth rate of microorganisms in bioreactors using sliding observers. In particular, a second-order sliding observer based on biomass concentration measurement is proposed. ...
